Nine years ago, Southampton traveled to Arsenal—still playing at Highbury then—and lost 1-6.

Saturday was a case of déjà vu for the Saints and a brilliant vindication of Arsene Wenger’s continued faith in his team and methods.

Jos Hooiveld turned in Kieran Gibbs’ cross into his own net to open the floodgates for the Gunners. Lukas Podolski and Gervinho (two) added to Nathaniel Clyne’s own goal while Theo Walcott provided the icing on the cake.

Daniel Fox pulled one back for Southampton before the second half, but Saturday night was all about Arsenal.

Just a couple of weeks ago, in the aftermath of a convincing away win over Liverpool, I suggested how Arsenal could cement a top-four finish this season.

A truly dominant display over Nigel Adkins’ Southampton shows that Arsenal can go one further and challenge for the English Premier League title this season.

Here are five reasons why. As usual, please feel free to have your say in the comments below.

Added Physicality to Complete Augment of Their Passing Game

To add to their passing approach, it seems Arsenal have also strengthened the physical side of their game.

Assistant coach Steve Bould has received plenty of credit for his work on the Arsenal defence. He should be equally commended for instilling a newfound discipline and resilience when handling their more physical opponents.

A key indicator of this was, of course, the Stoke City game, where Arsenal impressively held their own against erstwhile “rugby players” of an opponent. Against Southampton they showed more of the same.

Per Mertesacker, previously just a touch too slow for the Premier League, and Thomas Vermaelen, who has returned to his best, have been rocks in the center of defence, while Carl Jenkinson has shown a marked improvement over his hesitant debut season at right-back.

Three First-Teamers Still Yet to Return

While considering Arsenal’s strength in depth, don’t forget that Koscielny, Bacary Sagna and Jack Wilshere aren’t even back from injury yet.

When these three starting players in Wenger’s first-choice return, they will offer that big a difference to Arsenal’s overall quality and results.

If they've already dished a handing down to Southampton without even breaking sweat, what are they going to look like with a classy Koscielny rotating with Mertesacker; Sagna providing experience on the right; and Wilshere (hopefully) living up to his new No. 10 shirt?

Oh, and Francis Coquelin filled in for Abou Diaby—who was so impressive against Liverpool—on Saturday.

Your Thoughts

Of course, it’s still in the early days for Wenger, but all the signs are there for Arsenal to really mount a challenge of the higher order. We’ll find out in the coming weeks whether they can live up to this newfound hype.

What do you think? Do you think this is all just an overreaction? Or do you think Arsenal might actually end their silverware drought this season?
